Product Details
The Foxboro P0926KH, also cataloged as the P0926KH Modular Baseplate, operates as a dedicated hardware component for module mounting and backplane bus routing within Foxboro Evo Process Automation System architecture. It provides power connections and signal backplane execution across 2 Mbps standard fieldbus channels and 268 Kbps lines dedicated to 100 Series Fieldbus Modules (FBMs).

Process Loop Signal Conditioning and Channel Isolation
The Foxboro P0926KH incorporates dedicated backplane isolation channels designed to decouple high-frequency digital communications from field-side wiring loops. By isolating the internal dual 24 VDC distribution paths from field I/O connections, the baseplate prevents common-mode noise and ground loop currents from interfering with 4-20 mA HART loop protocol signaling across connected control modules.
Frequently Asked Questions
Q: Does the P0926KH support simultaneous operation of 200 Series modules and legacy 100 Series FBMs?
A: Yes, the backplane integrates dual communication paths running at 2 Mbps for standard modules and 268 Kbps specifically mapped for legacy 100 Series FBM signal processing.
Q: How is power redundancy maintained across the baseplate terminals?
A: The board features discrete primary and secondary 24 VDC bus connections with internal diode isolation, ensuring uninterrupted backplane power if one supply feed fails.
Field Installation Guidelines
Mount the baseplate securely onto standard DIN rails in either vertical or horizontal orientations. Verify that DIN-rail grounding clamps make direct metal-to-metal contact with an unpainted, grounded metallic backpanel to establish an effective protective earth connection.
Connect both primary and secondary 24 VDC feeds using independent, fused power lines. Ensure all fieldbus communication cables maintain proper shielding with drain wires terminated to a single chassis earth point. When passing field cables into panel enclosures, verify that NPT conduit fittings achieve a minimum 5-thread engagement to maintain enclosure mechanical integrity.
